and S100, connecting the user mobile terminal with a preset indoor Bluetooth iBeacon, and acquiring the current position of the user in real time.
Today, with the rapid development of information technology, technologies such as indoor positioning, path planning, mobile communication and cloud computing are developed in a blowout manner, and play an important role in different industry fields and application scenes. The intelligent evacuation and rescue system based on the fire-fighting Internet of things integrates the technology with the existing fire-fighting Internet of things technology, and constructs an intelligent evacuation and rescue system based on the fire-fighting Internet of things with functions of real-time rescue command and scheduling, automatic evacuation of people and the like by means of real-time fire-fighting Internet of things data, accurate personnel position and navigation and convenient mobile communication means.
Specifically, the invention adopts the Bluetooth equipment to position the user, thereby acquiring the specific position of the user in real time. The Bluetooth equipment in the invention is Bluetooth iBeacon, and the user is a person carrying a mobile terminal (such as a mobile phone), including trapped persons, fire rescue personnel and the like. Because bluetooth equipment passes through high performance lithium cell power supply, can last more than 3 years of working under the normal condition, do not receive the power supply when the conflagration takes place and influence. Moreover, the Bluetooth equipment carries out personnel position conversion through a three-point positioning algorithm, the fault tolerance of the system to the Bluetooth equipment is strong, and the final positioning result cannot be influenced even if part of the Bluetooth equipment cannot work normally. And the appearance design of equipment links components and parts and base through the magnet, and it is all very convenient no matter equipment maintenance, change to entire system's life has been ensured. And in the aspect of front-end equipment installation, no weak current line is laid, the whole deployment and installation time is short, and the influence is small.
Furthermore, the plurality of Bluetooth iBeacons are arranged in the indoor space in advance, the Bluetooth iBeacon is a three-point positioning algorithm based on Bluetooth 4.0, and due to the low power consumption characteristic of Bluetooth 4.0, the ideal positioning working distance of the Bluetooth iBeacon is recommended to be within 8 meters. According to the algorithm principle, when the target position is surrounded and covered by more than three Bluetooth iBeacons to achieve the best positioning effect, the setting principle of the embodiment is to divide the space into small spaces according to a proper distance by using the Bluetooth iBeacon.

Preferably, the map engine is combined with the fire protection internet, so that the fire alarm point and the barriers of the indoor space are displayed on the map, and trapped persons and rescue persons can know the accurate positions of the fire alarm and equipment failure of the indoor space at the first time. In addition, the invention also shows the positions of public facilities, fire-fighting facilities and equipment on the map, thereby facilitating emergency command and fire scene fighting.
Further, in step S300, the mobile terminal starts a navigation function, automatically plans an evacuation rescue route according to the acquired indoor map data, and avoids fire occurrence points and obstacles in real time.
In specific implementation, after the mobile terminal acquires the map of the indoor space, the accurate positions of the fire alarm point and the obstacle point on the map are acquired. And linking an escape passage preset in the indoor space with the fire alarm point and the barrier point, and planning a path by combining the current position information of the user and applying a path planning algorithm to obtain an evacuation rescue route with the shortest distance. The path planning algorithm in the invention is designed according to the relevant specifications and requirements of fire evacuation, and the following points are followed in the path planning process: and the personnel retreat according to the fire prevention subarea, avoid the fire and the barrier in real time and have the shortest path distance. Therefore, the invention carries out path planning through the navigation technology and avoids fire alarm points and barrier points in real time in the path planning process, thereby providing a shortest, safest and quickest escape or rescue channel for users (trapped people or rescue personnel).
